In the new issue of Regulation, economist Pierre Lemieux argues that the recent oil price decline is at least partly the result of increased supply from the extraction of shale oil. The increased supply allows the economy to produce more goods, which benefits some people, if not all of them. Thus, contrary to some commentary in the press, cheaper oil prices cannot harm the economy as a whole.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

Use Only U.S. Law to Interpret the U.S. Constitution

This fall, the Supreme Court will hear two cases involving Eighth Amendment challenges to the sentencing of juveniles to life without parole (“LWOP”) – Graham v. Florida and Sullivan v. Florida – claims that these types of sentences are “cruel and unusual.” Cato takes no position on the wisdom of these types of sentences, but when evaluating their constitutionality the Court should only consider American law.

That is, regardless of the criminological or moral merits of juvenile LWOP sentences, the Supreme Court ought not consider non-binding provisions of international human rights treaties and customary international law in its analysis (as it has in cases like Roper v. Simmons and Atkins v. Virginia). To that end, Cato joined the Solidarity Center for Law and Justice, the Sovereignty Network, and 10 other groups in a brief urging the Court to limit its constitutional analysis to domestic law and the decisions of U.S. courts.

Our brief argues that the Court should leave to the political branches the decision of whether to transform international norms into domestic law and only allow duly ratified international agreements to override domestic law – in the way the Court has set out in cases such as Medellin v. Texas. It further contends that if the Court believes this is one of the rare cases where international norms are relevant, it should follow the test it laid out in Sosa v. Alvarez Machain, which addressed the (unrelated) Alien Tort Statute: The relevant norm must be widely accepted by the civilized world and as clearly defined as the historic “law of nations” norms regarding safe conduct permits, ambassadorial rights, and piracy on the high seas.

The brief also cautions that reliance on non-binding and indefinite international norms will undermine the democratic process and rule of law, casting considerable uncertainty over many U.S. laws.

More generally, while looking to foreign and international example is prudent when designing constitutions and drafting legislation – or even adjudicating complex international legal disputes – it is simply not relevant to interpreting the nation’s founding document.
